Abstract :
Our proposed approach for increasing the transmission capacity is to reduce the channel spacing of a DWDM-direct system to the minimum while keeping the employed optical band-pass filter technologies. For the DWDM-direct system with 55 GHz FBG a satisfactory performance is achieved with a 50 GHz channel interval at the 10 Gbit/s data transmission speed leading to the increase of spectral efficiency for overall system from 0.18 bit/s/Hz to 0.2 bit/s/Hz.
